module: synchronize
version_added: "1.4"
short_description: A wrapper around rsync to make common tasks in your playbooks quick and easy.
description:
- C(synchronize) is a wrapper around rsync to make common tasks in your playbooks quick and easy. It is run and originates on the local host where
Ansible is being run. Of course, you could just use the C(command) action to call rsync yourself, but you also have to add a fair number of
boilerplate options and host facts. C(synchronize) is not intended to provide access to the full power of rsync, but does make the most common
invocations easier to implement. You `still` may need to call rsync directly via C(command) or C(shell) depending on your use case.
options:
src:
description:
- Path on the source host that will be synchronized to the destination; The path can be absolute or relative.
required: true
dest:
description:
- Path on the destination host that will be synchronized from the source; The path can be absolute or relative.
required: true
dest_port:
description:
- Port number for ssh on the destination host. Prior to ansible 2.0, the ansible_ssh_port inventory var took precedence over this value.
default: Value of ansible_ssh_port for this host, remote_port config setting, or the value from ssh client configuration if none of those are set
version_added: "1.5"
mode:
description:
- Specify the direction of the synchronization. In push mode the localhost or delegate is the source; In pull mode the remote host in context
is the source.
choices: [ pull, push ]
default: push
archive:
description:
- Mirrors the rsync archive flag, enables recursive, links, perms, times, owner, group flags and -D.
type: bool
default: 'yes'
checksum:
description:
- Skip based on checksum, rather than mod-time & size; Note that that "archive" option is still enabled by default - the "checksum" option will
not disable it.
type: bool
default: 'no'
version_added: "1.6"
compress:
description:
- Compress file data during the transfer. In most cases, leave this enabled unless it causes problems.
type: bool
default: 'yes'
version_added: "1.7"
existing_only:
description:
- Skip creating new files on receiver.
type: bool
default: 'no'
version_added: "1.5"
delete:
description:
- Delete files in C(dest) that don't exist (after transfer, not before) in the C(src) path. This option requires C(recursive=yes).
type: bool
default: 'no'
dirs:
description:
- Transfer directories without recursing
type: bool
default: 'no'
recursive:
description:
- Recurse into directories.
type: bool
default: the value of the archive option
links:
description:
- Copy symlinks as symlinks.
type: bool
default: the value of the archive option
copy_links:
description:
- Copy symlinks as the item that they point to (the referent) is copied, rather than the symlink.
type: bool
default: 'no'
perms:
description:
- Preserve permissions.
type: bool
default: the value of the archive option
times:
description:
- Preserve modification times
type: bool
default: the value of the archive option
owner:
description:
- Preserve owner (super user only)
type: bool
default: the value of the archive option
group:
description:
- Preserve group
type: bool
default: the value of the archive option
rsync_path:
description:
- Specify the rsync command to run on the remote host. See C(--rsync-path) on the rsync man page.
- To specify the rsync command to run on the local host, you need to set this your task var C(ansible_rsync_path).
rsync_timeout:
description:
- Specify a C(--timeout) for the rsync command in seconds.
default: 0
set_remote_user:
description:
- put user@ for the remote paths. If you have a custom ssh config to define the remote user for a host
that does not match the inventory user, you should set this parameter to "no".
default: yes
use_ssh_args:
description:
- Use the ssh_args specified in ansible.cfg
type: bool
default: 'no'
version_added: "2.0"
rsync_opts:
description:
- Specify additional rsync options by passing in an array.
default:
version_added: "1.6"
partial:
description:
- Tells rsync to keep the partial file which should make a subsequent transfer of the rest of the file much faster.
type: bool
default: 'no'
version_added: "2.0"
verify_host:
description:
- Verify destination host key.
type: bool
default: 'no'
version_added: "2.0"
private_key:
description:
- Specify the private key to use for SSH-based rsync connections (e.g. C(~/.ssh/id_rsa))
version_added: "1.6"
link_dest:
description:
- add a destination to hard link against during the rsync.
default:
version_added: "2.5"
notes:
- rsync must be installed on both the local and remote host.
- For the C(synchronize) module, the "local host" is the host `the synchronize task originates on`, and the "destination host" is the host
`synchronize is connecting to`.
- The "local host" can be changed to a different host by using `delegate_to`. This enables copying between two remote hosts or entirely on one
remote machine.
- >
The user and permissions for the synchronize `src` are those of the user running the Ansible task on the local host (or the remote_user for a
delegate_to host when delegate_to is used).
- The user and permissions for the synchronize `dest` are those of the `remote_user` on the destination host or the `become_user` if `become=yes` is active.
- In 2.0.0.0 a bug in the synchronize module made become occur on the "local host". This was fixed in 2.0.1.
- Currently, synchronize is limited to elevating permissions via passwordless sudo. This is because rsync itself is connecting to the remote machine
and rsync doesn't give us a way to pass sudo credentials in.
- Currently there are only a few connection types which support synchronize (ssh, paramiko, local, and docker) because a sync strategy has been
determined for those connection types. Note that the connection for these must not need a password as rsync itself is making the connection and
rsync does not provide us a way to pass a password to the connection.
- Expect that dest=~/x will be ~<remote_user>/x even if using sudo.
- Inspect the verbose output to validate the destination user/host/path
are what was expected.
- To exclude files and directories from being synchronized, you may add
C(.rsync-filter) files to the source directory.
- rsync daemon must be up and running with correct permission when using
rsync protocol in source or destination path.
- The C(synchronize) module forces `--delay-updates` to avoid leaving a destination in a broken in-between state if the underlying rsync process
encounters an error. Those synchronizing large numbers of files that are willing to trade safety for performance should call rsync directly.
- link_destination is subject to the same limitations as the underlaying rsync daemon. Hard links are only preserved if the relative subtrees
of the source and destination are the same. Attempts to hardlink into a directory that is a subdirectory of the source will be prevented.
